So you found a bug in ISC DHCP or plan to develop an extension and want to send us a patch? Great!
This page will explain how to contribute your changes smoothly.
-## Writing a patch
+Here's a quick list of how to contribute a patch:
+
+1. **create account** on [gitlab](https://gitlab.isc.org)
+2. **open an issue** in [this project](https://gitlab.isc.org/isc-projects/dhcp/issues/new), make sure
+ it describes what you want to fix and **why**. ISC DHCP is very mature code, with a large installed base.
+ We are fairly conservative about making changes unless there is a very good reason.
+3. **ask someone from the ISC team to give you a 'project allocation' so you can to fork ISC DHCP in our repo** (ask on the issue - mention @tomek, @vicky, @ondrej
+ or @godfryd if it seems we haven't noticed your request)
+4. **fork the DHCP master branch**: go to the DHCP project page, click the [Fork button](https://gitlab.isc.org/isc-projects/dhcp/forks/new).
+ If you can't, you didn't complete step 3. It helps to include the issue number and subject in the branch name.
+5. **Implement your fix or feature, in your branch**. Make sure it compiles, has unit-tests,
+ is documented and does what it's supposed to do.
+6. **Open Merge Request**: go to the DHCP project [merge requests page](https://gitlab.isc.org/isc-projects/dhcp/merge_requests), and
+ click [New merge request](https://gitlab.isc.org/isc-projects/dhcp/merge_requests/new). If you
+ don't see the button, you didn't complete step 3.
+7. **Participate in the code review**: Once you submit the MR, someone from ISC will eventually get
+ to the issue and will review your code. Please make sure you respond to comments. It's likely
+ you'll be asked to update the code.
+
+See the text below for more details.
+
+
+## Create an issue
+
+The first step in contributing to ISC DHCP is to [create an issue](https://gitlab.isc.org/isc-projects/dhcp/issues/new), describing the problem, deficiency
+or missing feature you want to address. It is important to make it very clear why the specific change
+you are proposing should be made. ISC DHCP is very mature code, with a large and somewhat inert installed base.
+We are very cautious about introducing changes that could break existing functionalty. If you want to fix
+multiple problems, or make multiple changes, please make separate issues for each.
+
+## Plan your changes
Before you start working on a patch or a new feature, it is a good idea to discuss it first with
-DHCP developers. You can post your questions to the [dhcp-workers](https://lists.isc.org/mailman/listinfo/dhcp-workers)
-or [dhcp-users](https://lists.isc.org/mailman/listinfo/dhcp-users) mailing lists. The dhcp-users is
-intended for users who are not interested in the internal workings or development details: it is
-OK to ask for feedback regarding new design or the best proposed solution to a certain problem.
-This is the best place to get user's feedback. The internal details, questions about the code and
-its internals are better asked on dhcp-workers. The dhcp-workers is a very low traffic list.
-
-OK, so you have written a patch? Great! Before you submit it, make sure that your code compiles.
-This may seem obvious, but there's more to it. You have surely checked that it compiles on your
-system, but ISC DHCP is a portable software. Besides Linux, it is compiled and used on relatively
-uncommon systems like OpenBSD. Will your code compile and work there? What about endianness? It is
-likely that you used a regular x86 architecture machine to write your patch, but the software is
-expected to run on many other architectures. For a complete list of systems we build on, you may
-take a look at the [Jenkins build farm report](https://jenkins.isc.org/view/isc-dhcp/).

-## Running unit-tests
+DHCP developers. You may benefit from reading the [ISC DHCP Developer's Survival Guide](https://gitlab.isc.org/isc-projects/dhcp/wikis/home)
+posted on the wiki page for this repo.
+
+You can post questions about development on the [dhcp-workers](https://lists.isc.org/mailman/listinfo/dhcp-workers)
+or [dhcp-users](https://lists.isc.org/mailman/listinfo/dhcp-users) mailing lists. Dhcp-users is
+intended for users who are not interested in development details: it is appropriate to ask for

+questions about the code and its internals are better asked on dhcp-workers. The dhcp-workers

+
+## Create a branch for your work
+
+These instructions assume you will be making your changes on a branch in the ISC DHCP Gitlab
+repository. This is by far the easiest way for us to collaborate with you. While we also maintain a presence
+on [Github](https://github.com/isc-projects/dhcp), ISC developers rarely look at Github, which is
+just a mirror of our Gitlab system.
+
+ISC's Gitlab has been a target for spammers, so it is set up defensively. New users need permission
+from ISC to create new projects. We gladly do this for anyone who asks and provides a good reason.
+"I'd like to fix bug X or develop feature Y" is an excellent reason. To request a project
+allocation in ISC's Gitlab, just ask for it in a comment in your issue. Make sure
+you tag someone at ISC (@tomek, @godfryd, @vicky or @ondrej). When you write a comment in an issue or
+merge request and add a name tag on it, the user is automatically notified.
+
+Once you are given a 'project allocation' in our Gitlab, you can fork ISC DHCP and create a branch.
+This is your copy of ISC DHCP and is where you will make your changes. Go to the DHCP project page,
+click the [Fork button](https://gitlab.isc.org/isc-projects/dhcp/forks/new) and you will be prompted
+to name your branch. It helps to include the issue number and subject in the branch name. You can make
+changes to this branch without worrying that you will impact the master branch - commit priviliges
+are restricted so you cannot accidentally alter the master branch.
+
+Please read the [Gitlab How-To](https://gitlab.isc.org/isc-projects/dhcp/wikis/processes/gitlab-howto) for ISC DHCP.
+
+## Implement your change
+
+
+
+## Compile your code
+
+We don't yet have continuous integration set up for ISC DHCP, so you have to check the compilation manually.
+ISC DHCP is used on a wide array of UNIX and Linux operating systems. Will your code compile and work there?
+What about endianness? It is likely that you used a regular x86 architecture machine to write your
+patch, but the software is expected to run on many other architectures. For a complete list of systems
+we build on, you may take a look at the [Jenkins build farm report](https://jenkins.isc.org/view/isc-dhcp/).
+
+## Run unit-tests
One of the ground rules in all ISC projects is that every piece of code has to be tested. For newer
projects, such as Kea, we require unit-test for almost every line of code. For older code, such as

-## Create an issue
-Since you want to change something in ISC DHCP, there's a problem, deficiency or a missing feature.
-Quite often it is not clear why specific change is being made. The best way to explain it is to
-[create an issue here](https://gitlab.isc.org/isc-projects/dhcp/issues/new). We prefer the original
-submitter fill them as he or she has the best understanding of the purpose of the change and may
-have any extra information, e.g. "this patch fixes compilation issue on FreeBSD 10.1". If there there
-is no MR and no gitlab issue, we will create one. Depending on the subjective importance and urgency
-as perceived by the ISC engineer, the issue and/or MR will be assigned to one of the milestones.

-## Merge Request (also known as sending your patch the right way)
-
-The first step in writing the patch or new feature should be to get the source code from our Git
-repository. The procedure is very easy and is [explained here](https://gitlab.isc.org/isc-projects/dhcp/wikis/processes/gitlab-howto).
-While it is possible to provide a patch against the latest stable release, it makes the review
-process much easier if it is for latest code from the Git master branch.
-
-Since you won't get write access to the ISC DHCP repository, you should fork it and then commit
-your changes to your own repo. How you organize the work depends entirely on you, but it seems
-reasonable to create a branch rather than working on your master. Once you feel that your patch
-is ready, please commit your changes and push it to your copy of ISC DHCP repo. Then go to DHCP project
